This study investigates the roles of cPML isoforms in HepG2 and MEF cell lines under the influence of TGF-β1. Using various plasmids and cell lines, we examine the expression levels of cPML, β-actin, and E2F1. We analyze the localization of cPML in both cytoplasmic and nuclear compartments, observing different behavior in Pml.+/+ and Pml.-/- conditions. The results indicate a complex relationship between cPML expression and TGF-β1 stimulation, shedding light on the regulatory mechanisms involved in tumorigenesis and cellular response.
